1 Claim.

The invention here disclosed relates to ma netic motors of the oscillatory type such as here'- tofore used for operating animated signs and the like.

Objects of the invention particularly are to provide a motor of this character which will be of the utmost simplicity, consisting of a minimum nuin ber of parts and these of simple, inexpensive, readily assembled construction.

Related objects are to provide a motor of the type indicated which will be relatively powerful for its size and which can be made up and sold at low cost.

Other desirable objects attained by the invention are set forth or will appear in the course of the following specification.

The drawing accompanying and forming part of the specification illustrates a present practical embodiment of the invention. Structure, however, may be modified and changed as regards the immediate illustration, all within the true intent and scope of the invention as hereinafter defined and claimed.

Fig. 1 in the drawing is a front elevation of the motor, with the cord for supplying energy thereto indicated as broken away;

Fig. 2 is a side or edge view of the motor;

Fig. 3 is a broken sectional detail illustrating the pivotal mounting for the swinging armature.

One of the special features of the invention is the making of the base of the motor of a single strip of sheet material, designated 55 in the drawing and shown as having its lower end curled at 6 into a substantially circular holder for the solenoid coil 1, and its upper end arched over at 8 and bent outwardly at 9 to provide a support for the pendulous armature.

The arcuately curved armature which cooperates with the coil is designated I!) and is of special construction in that the arm H which supports it is an integral portion of the same, connected with one end of the armature by an acutely angled integral bend [2.

The upper end of the integral supporting arm is shown as flattened on opposite sides at it so as to be smoothly held between the confining washers M, where it is engaged on the pivot pin IS. The latter is shown in Fig. 3 as headed over or riveted at opposite ends, and a tubular spacer I6 is shown engaged on the pivot pin, in back of the inner washer to locate the curved armature rod in centered relation in the coil.

With this construction the parts can be quickly and easily assembled with the assurance that the armature will swing freely into and through the solenoid coil.

A small mercury switch I1 is shown secured on the back of the supporting arm by a clip l8 beneath and in line with the spacer l6 and hence positioned in the clear between the front of the base and the back of the supporting arm.

(Cl. 172l26) The supporting arm may have one or any number of openings l9 therethrough for screws or other fastenings for attaching the movable portion of an animated sign or the like.

The mercury switch is connected in series relation with the solenoid coil by wiring 2E1, terminating in an attachment plug 2i for cooperation with an electric outlet.

The base strip 5 may have any number of openings therethrough for screws 2| or other fastenings for mounting this member in the inclined relation such as shown, Where the armature will hang normally in a position partly entered in the coil.

The invention has many advantages and particularly as to simplicity and low cost. The onepiece magnetic pendulum is a special factor in keeping the parts few in number. This member may be made of inexpensive iron rod and may be mounted with the use of a single fastening stud headed at one end and riveted at the other end.

When the parts are assembled and riveted as shown they will be firmly held together with the pendulum maintained in free swinging relation and the arched top portion of the bracket held against spreading or any movement that might throw the pendulum out of line.

What is claimed is:

A magnetic motor of the oscillating pendulum type comprising a single, straight, upright length of strip material having forwardly bent portions at opposite ends of the same, the forwardly bent portion at the lower end of said strip material being curled to form an integral seat, a solenoid coil seated in said forwardly bent portion at the lower end of the strip, an arcuate armature rod operative in said coil, said rod having an integral, angularly bent supporting arm portion acutely angled in respect to the concave side of said arcuate armature rod, said supporting arm portion at its upper end being pivo'tally mounted on the forwardly bent portion at the opposite, upper end of the strip, a switch element mounted on said supporting arm and connected to control cir cult through the coil and means for mounting the strip in an inclined relation for suspending the armature and the switch carried thereby in proper operative relation in respect to the coil.
